It only happens 12 times a century and won’t happen again for another 88 years.

Yet people in Worcester County, at least, don’t seem too excited about this century’s last alliteration date of 12-12-12.

Some say the ancient Mayan calendar’s cycle will stop and something significant will take place, such as cataclysmic events and the world’s rebirth on 12-12-12 or 12-21-12.

But Marcel Y. Blais, assistant math professor at Worcester Polytechnic Institute, says there is really nothing special about dates with matching days, months and years.

“This is a purely numerical issue, and there is no special significance inherent to these dates,” Mr. Blais said.

Dates in which the last two digits of the year, the month and the day are equal only happen once per year in years ending in 01, 02, 03, and so on, he said.

“After 12-12-12, we will not have a day with this property until 01-01-01 comes around again on Jan. 1, 2101, about 88 years from today,” Mr. Blais said. “Thirteen can’t be a month. It can only happen the first 12 years in a century.”

As for those who link the dates of 12-12-12 or 12-21-12 to doom and gloom and the end of the world, Mr. Blais chalks it all up to superstition.

“The whole Mayan calendar thing is just complete nonsense,” he said. “It is kind of silly, but people tend to be superstitious.”

A date to keep in mind, Mr. Blais said, that is fun and held dear by some of his mathematician friends at WPI is 3-14-15 — the first five numbers of pi, an irrational number that is the ratio of a circle’s circumference to its diameter.

“Keep in mind that on March 14, 2015, we will have Pi Day because pi’s first five digits are 3.1415,” he said. “That will be another fun one. At WPI, we take special pride in that number.”

It seems to be just another day, at least in Worcester County, for marriage.

City Councilor and Justice of the Peace George J. Russell said though it is an easy anniversary date to remember, he hasn’t received any calls from people wanting to tie the knot today.

“I’ve seen no increase at all,” he said. “There aren’t lines at the door for people wanting to have weddings.”

Paula J. Kwiatkowski, sales manager at the Chocksett Inn in Sterling, said she is seeing the same indifference to the date.

“I find that weekdays for special dates don’t seem to matter,” she said. “We get more bookings on the weekends.”

She said she doesn’t have any bookings for 12-21-12, either.

“Nobody was looking to get married before we all went,” she said, laughing about the end of the world prophecy linked to the Mayan calendar. “I’ve got one for Dec. 22, though.”

Sharon R. Onorato, director of sales at Mechanics Hall, said it had weddings booked on 8-8-08, but none today.

“Other years we had that kind of thing, but not this year,” Ms. Onorato said. “It could be true that people are staying away from it.”

David J. Rushford, city clerk and justice of the peace, said only two marriages were scheduled for today.
